To give a normal form?

Don't do it horizontally as suggest above. Vertical forms are read and filled in easier :)

I would have laid out the form in the table: labels in the left column, input fields in the right. If you want the decorations, even the entire form in a frame with rounded edges.

1) Make 2 columns.
2) "field is required" to do less and to wear on the field, clicking on field to remove this inscription.
3) something to do with captcha, for example to remove it and do the form submission via ajax
4) Mandatory fields are in bold, not required normal font.

Teachers is it better to arrange a drop-down list. Surely there is a ready sample.
